Recently we suggested a new ink-jet injection method. Feature of our method is to use impulsive force. We can generate a high-speed jet (200 m/s) and a highly-viscous jet (10,000 cSt) easily at a low price. In this method, bubbles are generated in the liquid when a strong impulsive force is given. It is difficult to control the bubble inception that causes variations in jet. To control the bubble inception, we came up with a method to introduce PVA gel including bubbles into the liquid. We successfully suppress bubble generation and control the bubble acceleration effect on the jet velocity.
